Sorry if this was covered, but emulators for Omega

I got an Omega today, currently copying some libraries to the card I picked up and it dawned on me that I've seen some people comment on one thing, and not another I used to do. Long ago I had the first EZ4 and then the first revision of it (still pre-black shell.) Back then you had to use that app and copy games to it that way and then other apps to make up to 32MB .gba rom clusters of files for emulators like PocketNES and the Goombas.

I saw this one natively does NES and GB+GBC too...
